3M 7738MM Arc-proofing Tape
Scotch® Fire-Retardant Electric Arc Proofing Tape 77 Series provides high-energy power and control cables with essential arc fault protection. Designed for exposed and vulnerable locations, this elastomeric tape creates a durable, insulating char barrier when subjected to high temperatures, effectively shielding cables from fault arc heat and flames within approximately 20 inches. Its conformable, unsupported elastomer allows for virtually wrinkle-free application over irregular shapes, ensuring consistent coverage and space-saving thin profile. Resistant to water, salt water, acids, sewage, and UV light, the tape lasts for the cable's lifetime and can be reused, making it ideal for critical electrical infrastructure.
